Lupinus arboreus

The tree lupin, Lupinus arboreus, is a beautiful evergreen shrub, bearing silky shoots and grey-green leaves. From late spring to summer, fragrant yellow, sometimes blue, flowers appear. These are similar to the cultivated varieties of lupin but are held in looser panicles. As with cultivated lupins, Lupinus arboreus flowers are attractive to bumblebees.

For best results grow Lupinus arboreus in well-drained soil in full sun.
